Hi .=20
This is actually part of my earlier mail regarding network interrupts.=20
Assuming that 1500 byte packets are arriving on a 266 Mhz PII at the =
full rate of 100 Mbps. It would mean a packet and hence an interrupt =
every 0.12 ms.=20
WHat happens is this -=20
there are 2 sockets on one machine (266 Mhz ) recieving packets from 2 =
sources (233 Mhz) continuously. The ethernet driver (via-rhine) says - =
eth0: Something wicker happened - too much work in interrupt (error =
number 1081). What exactly is happening? The top half handling would be =
(I assume) minimal. Is it that the machne is not able to handle =
interrupts this frequently?
Another thing - all this is in kernel 2.0.36. In kernel 2.2.2, there is =
a facility for hardware flow control. Would this mean that theres no =
need for flow control at upper layers (like TCP flow control - tranport =
layer)??
Thanks
Akshay
